Description

The AP7362 is a 1.5A adjustable output voltage linear regulator with ultra-low dropout. The device includes pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry. The integrated Enable block allows the part to be turned on and off via a logic signal. A logic high level on EN turns the device on and a logic low turns the part off.

The low dropout voltage characteristics and fast transient response to step changes in load make it suitable for low voltage microprocessor applications. The typical quiescent current is approximately 0.5mA and changes little with load current. The built-in current-limit and thermal-shutdown functions prevent damage to the IC in fault conditions.

This device is available in U-DFN2030-8 and SO-8EP packages.
